Caffeine, Coffee, and Tea: How Do They Impact Eye Pressure? Caffeine is one of the most widely consumed substances worldwide, found in coffee, tea, energy drinks and many soft drinks.

Decaffeinated coffee is regular coffee beans that have had most of their caffeine removed before roasting and brewing. The removal can be done with methods such as water processing, carbon dioxide extraction, or solvent-based techniques, and each method can affect flavor and residual caffeine levels. Although called decaffeinated, it usually still contains a small amount of caffeine, so it is not completely caffeine-free. People choose it to avoid the stimulating effects of caffeine while still enjoying the aroma and taste of coffee. It is often selected by those who are sensitive to caffeine, have trouble sleeping, are pregnant, or need to limit stimulant intake for medical reasons. Decaffeinated coffee retains many of the same antioxidants and flavor compounds as regular coffee, so it can provide similar potential health benefits without the same energy boost. Some drinkers notice subtle taste differences because the decaffeination process can alter the beans’ natural oils and acids. When buying, it helps to check the decaffeination method and roast date, since both influence flavor quality. If you must avoid even trace caffeine, read labels carefully because residual amounts vary by brand. Overall, decaffeinated coffee offers a way to enjoy coffee’s flavor and social ritual with less impact on sleep, heart rate, and jitteriness.
